Keyboard shortcuts for non-iPhone browsers are denoted in parens ().
Mode keys:
ACclears the number or stack and resets the state of the calculator. (Escape)
CEclears the number currently being entered. (Escape)
Fncycles through showing different sets of operation keys, such as trig and exponential operations. (`)
Invinverts the function of various operation keys, such as squares and square roots. (i)
Modeshows optional display mode and alternate base mode keys. (m)
DRGcycles between Degree, Radian and Gradian modes, converting the current number. (D)
Memin Algebraic mode, exposes a set of memory operation keys.
RPNswitches between Algebraic and Reverse Polish Notation modes. (R)
Binchanges to Binary alternate base mode. (m - b)
Octchanges to Octal alternate base mode. (m - o)
Decchanges to primary Decimal base mode. (m - d)
Hexchanges to Hexadecimal alternate base mode. (m - h)
Normswitches to Normal display mode. (m - n)
Fixswitches to Fixed decimal display mode. (m - f)
Sciswitches to Scientific Notiation display mode. (m - s)
Engswitches to Engineering Notation display mode. Like Sci mode, except the exponent is always a power of 3. (m - e)
0-12in the mode screen, these let you specify the precision of Fix, Sci, and Eng display modes.
Memory keys:
M+adds the current number to tthe memory buffer.
M–subtracts the current number from the memory buffer.

cos-1gets the arccosine of the given number. (inv - C)
tan-1gets the arctangent of the given number. (inv - T)
πenters the value of Pi. (p)
Bitwise operator keys:
ANDperforms a bitwise AND of two numbers. (&)
ORperforms a bitwise OR of two numbers. (|)
XORperforms a bitwise Exclusive-OR of two numbers. (^)
NOTperforms a bitwise NOT on all 32 bits in the number. (!)

<<nperforms a bitwise left shift by n bits.
>>nperforms a bitwise right shift by n bits.
RoLperforms a bitwise roll left by 1 bit. ([)
RoRperforms a bitwise roll right by 1 bit. (])
RnLperforms a bitwise roll left by n bits.
RnRperforms a bitwise roll right by n bits.
RPN mode stack keys:
Rollrolls the topmost stack item to the bottom of the stack. (q)
Swapswaps the two bottommost numbers on the stack. (w)
Dropdrops the bottommost number off of the stack. (z)
EnterPushes the number currently being entered onto the bottom of the stack. (Enter)
Miscellaneous keys:
1/xgets the reciprocal of the given number. (\)
x!gets the factorial of the given integer. (!)
%performs percentage based calculations when used with +, –, × and ÷ operators. (%)
intgets the integer part of the given number.
fracgets the fractional part of the given number.
±inverts the sign of the current number or exponent. (s)
Expbegins exponent entry mode, to allow entering scientific notion numbers. (E)
